The current chairman of the National Republican Congressional Committee could find himself out of that position after Election Day if critics get their way, according to Politico.

Republicans are expected to gain as many as 10 seats on Tuesday, but Oregon Rep. Greg Walden has nevertheless been criticized for the GOP's strategy and tactics in the final weeks of the campaign, while numerous NRCC staffers are disenchanted.

Specifically, many in the party are unhappy that Democrats have consistently out-raised Republicans during the cycle, and it is expected that the party will fall short of its ambitious goal of securing a majority of 245 seats.

Texas Rep. Roger Williams and Illinois Rep. Aaron Schock have both signaled they are interested in the job. Williams is one of the party's fundraisers and has been trying to build support for himself. Schock, also a fundraiser, has also mentioned to colleagues that he would be interested in the position, though he has also expressed an interest in running for governor, Politico reported.

In the event that Walden decides to step down, Reps. Lynn Westmoreland of Georgia and Ann Wagner of Missouri would also consider running, according to Politico.

House Speaker John Boehner, however, is one of Walden's supporters, and allies credit him with setting up an effective operation that will successfully increase the GOP's majority.

"Chairman Walden is working tirelessly on behalf of our candidates. He's a big reason why we've got an opportunity to win a larger House majority this November," Cory Fritz, Boehner's top political aide, told Politico.

A spokeswoman for the NRCC robustly defended Walden's leadership.

"Chairman Walden is fully focused on electing Republican candidates on November 4th," Andrea Bozek told Politico. "He is consistently out on the campaign trail helping candidates all across the country and appreciates how many of his colleagues are stepping up to help in a very effective and positive ways."

Outside groups and super PACs have had more influence in spending than the party committees during this cycle, but the Democratic Congressional Campaign Committee out-raised the NRCC by $38 million.

Nevertheless, others say it would be unfair for Walden to be blamed for Democrats outperforming Republicans in fundraising.

"Listen, all this can't be laid on [Walden]; some of this is the speaker too," one GOP lawmaker told Politico. "But it's just scandalous how badly the NRCC is being out-raised. It's kind of unbelievable. We have got to do a lot better, whether it's Walden over there or whoever it is."

Meanwhile, Boehner has been traveling the country in the final weeks of the campaign in an effort to win as many seats as possible. He has also been a highly-effective fundraiser, pulling in roughly $100 million for the party.
